This is one of the best, clear explanation and break down of the "Manual" Brakes. I will continue to watch your other Videos. My Pedal ratio went to the floor after installing new Brakes and Master Cylinder and Bleeding till my foot was sore. Found out from your Videos it could be the Brake Pedal, Push rod may be to short, not reaching and engaging the Master Cylinder plunger. Bought a Universal Pushrod (Adjust longer). Did the trick. Thank you.
Definitely learned something today; very informative. Right in line with what I want on my 69 Camaro build. I’ll be running a set of Brembo’s from a 6th gen Camaro SS/1LE. All four corners. 6 piston up front and 4 in the rear. Based on your info, I think my best option is the 7/8 bore. Would you agree or what else might you recommend? The car will be street legal but also will see a good bit of time on the road course.
Very informative video. I have 67 camaro pro touring build I've done myself. With a 15/16 wilwood mc, stock camaro pedal utilizing the top pedal hole and 6 piston front and 4 piston rears with wilwood proportion valve. My pedal is firm, and i feel like i really need to apply pressure to get ok stopping force. Any insight on what might be needed for better brake performance?
Man, thats the best and most sensible video Ive seen on the subject. I have a 70 Torino with stock disc front and stock Ford disc rear. I want to go to manual brakes, I have a 6:1 pedal ratio (used to be a bellcrank setup) Would I be on the right path using a Wilwood 15/16" and Wilwood prop valve to give me good safe brakes? Thanks and love your work 👍👍
Sometimes, depending on the build, it may not allow the room to run the proper pedal ratio. Or personal preference, if vacuum and booster size are correct, some may like the feel of a modern boosted system for a street car. The key is making the correct pressure without have to make too much effore
hey good video... however where are the follow up videos mentioned? I feel like I only got half of what I need. I was hoping to learn more on how caliper size comes into play
Do you think a 15/16 mc with a 4 piston caliper (1.65in² per piston) and a 6:1 pedal ratio will have a good pedal feel and stopping power? Good information on using 4 piston calipers aoth manual brakes is hard to come by, thank you!
@@cameronpierce5188 1.75" four piston caliper in the rear and 1.65" four piston in the front? That is not a good combo with more rear clamping force on a front engine car or truck.
i got a t bucket roadster they put the master cly down by the rear of the trans they have the push rod 14" long from the pedal. and the removed most of the springs on the drums so they are like trailer brakes amyone see a problem with this????
I put a bear 2 piston clasic kit with there 15/16 master cylinder and one piston disc in back and I got the gm brake pedal with 2 holes on for manual brakes 6to 1 ratio and my don't stop at all talked to willwood they say put the 4 piston in front and that should fix it I want manual brakes
I know this video is older but I have a 66 mustang. I’m upgrading to 6 piston brembo front calipers 15 inch rotors. The rear is single piston calipers with 14 inch rotors. I’m torn between using a 7/8 bore master cylinder or 15/16? The pedal ratio is 6:1. I’m manual brakes by the way. Any info would be helpful
@@rmjmotoring the front 6 pistons are 36mm and the rears are single 43mm pistons. The front brakes are from a s550 mustang and the rears are from s197. Does that help? This subject is a little confusing to me.

I did learn something from this master class on manual brakes. Thanks!!

Yes
Terrific info. Given that the manual can reach the pressures as the vac assist booster, why wouldnt I choose a simpler manual setup?

@cameronpierce5188 what size pistons are on the back caliper
@@rmjmotoring 1.75"
@@cameronpierce5188 1.75" four piston caliper in the rear and 1.65" four piston in the front? That is not a good combo with more rear clamping force on a front engine car or truck.
@@rmjmotoring sorry shouldve specified, 4 piston calipers in the front and single piston in the rear
@@cameronpierce5188 ok makes more sense. 15/16 should be a good start

6:1 pedal ratio with a 15/16 bore master cylinder, using 100 pounds of leg force on the pedal should output about 800-900 psi. Which should be good
So u think I would better off with the willwood kit 4 pistons
@@MrDavidfig the Wilwood would be more efficient, but I suggest confirming the pressure at the caliper first
I did that last weak almost a 950 in front and 800 in back
@MrDavidfig pressures are where they need to be. Even on oem brakes it should stop. Unless there is an issue with the baer components
My brakes don't grab hard. Fron disc. Chevelle . Drum on the rear . Way too much peddle pressure. Is it a bad prop valve plz help???
@@stevekelly4103 most likely not. Prop valves do not add pressure.
